Applicationfiled June 28, 1893- Serial No. 279,019. (No model.) Patentedin Germany April 20, 1887, No. 43,549, and in v Austria-Hungary .Tuly10,1888,N0. 12,920 and No. 21,087.

To all whom it may concern.-

Be it known that I, FRANZ HOCHMUTH, of Dresden, in the Kingdom ofSaxony, in the German Empire, have invented certain new and usefulImprovements in Apparatus for Turning Malt on Kilns and for LikePurposes, of which the following is a specification, and for which Ihave obtained patents in Germany, No. 43,549, dated April 20, 1887, andin Austria-Hungary, No. 12,920 and No. 21,087, dated July 10, 1888.

This invention relates to rotary apparatus for periodically orcontinuously lifting and turning over grain, malt or other materialwhile spread out in a layer on a floor for the purpose of airing ordrying said material.

In carrying out my invention I employ a series of shovels attached to arotary shaft in a carriage to which is given a reciprocating movementback and forth over a floor on which the grain, malt or other materialis spread.

My improvement consists in the construction and means of controlling theoperations of said shovels as hereinafter described and claimed.

I will proceed to describe the improvement with reference to theaccompanying drawings and afterward set forth its novelty in the claim.

Figure 1 shows a cross section of the apparatus for lifting and turningthe malt which is spread in a layer on the perforated floorD. Fig. 2represents a partial front view of the same apparatus, the gearing forrotating the lifting and turning apparatus being in section. Fig. 3shows aside view of the gearing for rotating and advancing theapparatus. Fig. 4 is a ground plan partly in section corresponding withFigs. 2 and 3.

Similar letters of reference designate corresponding parts in all thefigures.

A is ahollow shaft extending over the width of the perforated floor orkiln D. The hollow shaft A rests at its two ends in bearings in the twosides of a carriage W. On one end of this shaft A, a chain wheel R isfixed over which passes an endless chain 8, which by means of thecounter chain wheels R is forced to enter into the teeth of the chainWithin these rails and above the bearings of the shaft A, racks n arefixed.

Upon the shaft A a pinion P is arranged, taking into the larger spurwheel T which is keyed on the same shaft with the pinion U which takesin the rack n. Thus the rotary motion of the shaft A is transmitted tothe carriage W by thewheels P T U and rack n,

causing the carriage to travel along over the kiln at a speed relativelyslow to the rotary motion of the shaft A.

On the shaft A are mounted arms B at the ends of each of which atwo-bladed shovel is hinged or pivoted so that the two blades :1: y ofeach of said shovels which are substantially at right angles to eachother, may enter into any of the positions-shown in Fig. 1. According tothe direction in which the carriage travels over the kiln D, the bladeor: or the blade y of each shovel will assume a position tangential to acircle having the axis of the shaft A for its center in which positionit will enter into the malt on the floor D and lift it while the otherblade 3 or x will occupy a position radial or approximately so to thesaid shaft and close to the arm B to which the shovel is pivoted. On thearms 13 there are loosely mounted annular slides or sliding pieces F.each provided with two projections 5, 6, one on each side of itsrespective arm. These slides will drop when the arm B comes into itslowest position and by dropping one of the projections will catch theone blade of the shovel which lies close to the arm while the otherblade digs into the malt for lifting the latter; the slide E will nowautomatically lock or retain the shovel in this position while risingwith the rotation of the shaft A, so that the shovel in so rising willlift the malt and will gradually allow the malt to fall or drop throughthe air until the arm B comes into such elevated position that the slide'E by its own weight slides back to ward the shaft A and thusautomatically releases the shovel leaving it free to turnon its pivot asindicated on the upperwarmB in;

one of the latter will always, come into ac-. tion, that is to say, toretain-the shovel with its load in due position whether the carriagewith the apparatus is travelinginrthecidirec= tion indicated by thearrow in Fig. 1 or traveling in the reverse direction. It is furthermoreobvious that the arms B on the shaft A should be placed or situated onthe latter'alternately -inw such. a manner that the shovels C will allowno part of the layer of mal-tto remain untouched so that all the malt islifted, airedand dropped al'li oven the surface of the kilnra What Iflclaimriasimy inventioni' is-k- In: an apparatusforqturning malt andother substances, the combination with a rotary shaft 3 and attachedarms, a series of twobladed shovels having their respective blades at anangle to each other and pivoted to'said arms, and slides on said armsfor automatically engaging either ,of the two blades of each of saidshovels with its respective arm for holding said shovels in operativepositionsrwhen loaded :and automatically releasing saidshovels andleaving them free to swing on said arms when unloaded, all substantiallyas herein set-forth.

In testimony that "I claim the foregoing as myinvention" T have-1 signedmyname in-presence of 'twoisubscribing witnesses.
